Thanks Akgo There are a lot of variables like what is your site fall across your building area, site access for machinery, ground conditions ( rock, clay etc) , if you go for the pier and beam option what will the flooring be ie concrete or yellowtongue etc. It's a bit of a "how long is a piece of string" question. Typically for the sites with say a 2-3m fall in our area of sydney with mixture of clay and some rock, assuming a split level design, we are finding that cut and fill with a waffle slab is the most cost effective option.

Re: Is there site cost for using pier and beam foundation? 11Dec 20, 2021 8:31 pm akgo Thank you for giving me some idea about site cost, Simeon. Is it better to do the geotech/ soil after the old house is knocked down or it doesn't matter? Thanks no problem With the geotech it really depends on how many boreholes you want them to take and what sort of rig they use, and what your site access conditions are like. As an example, the guy I use has a drill fixed on the back of a 79 series ute. As far as I know, project home companies do a soil test with a hand auger. If I were you I would do the test after demolition and get 3 - 4 boreholes across the site cheers Simeon Architectural Homes & Duplexes - specialising in custom designing homes to your budget Get a Free Onsite Consultation Today or send a PM for information, questions or advice.

Simeon Dont know how it is in Sydney, but every test ive seen done down in Melbourne by volume builders has been done with a ute mounted auger. Client pays for this anyway. Can't imagine a hand auger would be a good cost/benefit proposition Dark matter scientist, can breathe underwater, mind reader and can freeze matter just by willing it. Trust me, its in my sig. Re: Is there site cost for using pier and beam foundation? 14Dec 23, 2021 2:47 pm Usually the first test is done with a hand auger if you are lucky you may be able to do one in the drive with a drilling rig but sometimes thats not possible. After demolition the soil testing company will return with a ute drill rig to do more test with at least one where the old house was.It is a good idea to do at least one hole do to 2.5m-3m as there may be neighbouring tree or on site trees that will require the slab design to have piers.

So, the pier foundation wasn't large enough on the side it was leaning towards, and the NBN cable went through the pier, just… 8 12122 Just be careful with building stability during construction, that is when the structure may be weakened, refer to your engineering drawings for stability methodology. 1 7223 |
